摘 要

本论文是结合目前实际生产中，常常发现仅用通用夹具不能满足生产要求，用通用

夹具装夹工件生产效率低劳动强大，加工质量不高，而且往往需要增加划线工序，而专门设计两种夹具：铣床夹具和钻床夹具，主要包括夹具的定位方案，夹紧方案、对刀方案，夹具体与定位键的设计及加工精度等方面的分析。

本设计铣床夹具有良好的加工精度，针对性强，主要用于拨叉零件铣槽工序的加工。其具有夹紧力装置，具备现代机床夹具所要求的高效化和精密化的特点，可以有效的减少工件加工的基本时间和辅助时间，大大提高了劳动生产力，从而可以有效地减轻工人的劳动强度和增加劳动效率。钻床夹具具有提高生产率、扩大机床工艺范围、减轻工人劳动强度以及保证生产安全等特点。因此，对夹具知识的认识和学习以及设计新式的适合实际生产的夹具在今天显得尤为重要起来。

关键词：铣床夹具，钻床夹具，设计，高效

Abstract

The present paper is combing the actual production at present, which is that either using universal fixture cannot meet only production requirements or using universal fixture clamping work-piece to product is poor efficiency and powerful labor and not high processing quality or often it need to increase crossed process, to specially design two fixture: milling fixture and drilling fixture, mainly including schemes of fixture positioning, clamping and cutter, the design of the concrete and the TAB folder and the analysis of machining precision et al.

The milling fixture, having good processing precision and targeted, mainly is used to process dial the fork parts milling flutes. The fixture with clamping force device has the characteristics of efficiency and precision required by modern machine tools. It is so effectively to reduce the processing time and auxiliary time that greatly improve the labor productive, effectively reduce the labor intensity and increase the work efficiency as well. Drilling fixture is good for raising productivity, expanding machine machining scope, reducing labor intensity and ensuring the production safety. Therefore, it is especially important to learn and study the knowledge of fixture and design new suitable for practical production fixture nowadays.

Key words：milling fixture, drilling fixture, design, efficiency
